Cometabolism of ferrihydrite reduction and methyl-dismutating methanogenesis by .

Recent discoveries have shown that some species can reduce Fe(III), reshaping our understanding of ecophysiology. However, the specific minerals reduced, the products formed, and the underlying metabolic mechanisms remain elusive. Here, we report on the cometabolic process of Fe(III) reduction and methylotrophic methanogenesis in zm-15.

[N-terminal truncation of prenyltransferase enhances the biosynthesis of prenylnaringenin].

8-prenylnaringenin (8-PN) is a potent estrogen with high medicinal values. It also serves as an important precursor for many prenylated flavonoids. Microbial synthesis of 8-PN is mainly hindered by the low catalytic activity of prenyltransferases (PTS) and insufficient supply of precursors.
